Gateway system
First Claim
1. A system comprising:
- a gateway for subcutaneous injection of fluid, the gateway comprising a body with at least one through-going opening, at least one cannula and a restriction for microorganisms placed at a distal end of the at least one cannula or in the at least one through-going opening, the gateway having a proximal surface for contacting the patient'"'"'s skin and a distal surface;
an inserter device comprising a penetrating member and a biasing unit, the biasing unit adapted to urge the gateway from a retracted to a forward position when released;
a drug delivery device, the drug delivery device configured for passing through the restriction of the gateway, anda separate interface comprising an interface proximal surface corresponding to the distal surface of the gateway and an interface distal surface corresponding to a proximal surface of the delivery device;
wherein either the drug delivery device or the separate interface comprises an injection needle.

Abstract
This invention relates to an injection site or gateway or a system comprising such an injection site or gateway. In one form the invention concerns a system comprising an inserter device and a gateway for subcutaneous injection of fluid where comprises a distal surface (1a) corresponding to a proximal surface (1b) integrated with the inserter device. In another form the invention concerns a gateway for subcutaneous injection of fluid, which gateway comprises —a body (1) with at least one through-going opening (6) with an entrance and an outlet, and at least one cannula (3) and having a proximal end protruding from the lower side of the body; —and at the entrance of the through-going opening medication can be injected by a delivery device (20) which delivery device has protruding parts (22) which form an inner opening with a diameter di; wherein the surface of the entrance is shaped in such a way that the cross-section of the top part of entrance, i.e. from the top of the entrance to a position di/3 below the top, do not exceed di.
